Transcript of Newtons Laws as Applied to Amusement park ride

Newtons Laws As they apply to Roller Coasters The Titan is a roller coaster located in Six Flags over Texas. The Titan is a true thriller reaching speeds of up to 85 mph and over 255 feet tall. This mega roller coaster needed 2.8 million pounds of steel to create the supports to hold up the 5,300 feet of track.The ride lasts for a 3 minutes and 30 seconds but can cause extreme headaches. The park had to slow the coaster down because people were reporting sickness. The ride was built in 2001 and costs about 25,000,000. Giovanola is the builder of this steel giant. The ride can handle 1,600 riders per hour and the ride starts by pulling you up a 75 meter hill then dropping you 78 meters. From there the roller coaster enters a camel back turn and then enters a 540 degree helix. This is followed by another helix and turns. Background First Law of Motion The first law of motion states that an object in motion will stay in motion, and an object at rest will stay at rest unless acted upon by an outside force. This law is also known as the law of inertia. Image This is the part of the braking system for a roller coaster EXPLANATION The roller coaster car is in motion and will stay in motion until acted upon by an outside force. While the car is going forward the car will continue to go forward until the brakes are applied, this would create unbalanced force, being in motion also is an unbalanced force. The balanced force is when the car is at a stop and forces are equal. Roller coasters are designed to not allow the car to stop in the middle of the track. When you reach the end of the roller coaster there is a demonstration of this. The car comes to a sudden stop and you are pulled forward this is because the car may have a force stop it, however no force was applied to you. You continue to move forward, this is because of inertia, you have a tendency to remain unchanged and to continue doing what you were doing.The first law is also commonly referred to as the law of inertia. There are many forces that will change the motion of the roller coaster such as gravity and friction. Second Law of Motion The second law of motion states that the net force is equal to mass times acceleration. In other words the acceleration is proportional to the force applied as well as the mass of the object. Picture Explanation The second law applies to roller coasters because acceleration can rapidly increase and change direction. When you are going up a hill you are not accelerating, but when you go down the hill there is a rapid acceleration. The brakes can decrease acceleration, the rails change direction of acceleration, and gravity pulls the roller coaster down. Gravity is what makes roller coasters fun, gravity also has a direct effect on speed and acceleration.This laws also applies because the more mass on the roller coaster, the more force it will take the roller coaster to make the cars accelerate at the same rate as an empty car, Video of the Titan Third Law Newton’s 3rd laws states that for every action force, there is an opposite and equal reaction force. These forces come in pairs. Picture Explanation The third law applies to roller coasters. This law includes action and reaction forces which can include loops and going up and down hills. When you go up you have the action force and when you zoom down you have the reaction force. Another example of this would be loops, the track gives you centripetal force(action force) and the rails direct you(the reaction force). Another action and reaction pair is you pushing on the seat and the seat pushing on you.
